PORTABLE OVEN.

SPECIFICATION forming part of Letters Patent No. 711,285, dated October 14, 1902.

Application filed February 21, 1902. Serial No. 95,102. (No model.)

To rbi/Z whom, t may concer-71,:

Be it known that I, JOHN R. CARTER, ofAugusta, in the county of' Bracken and State of Kentucky,have invented certain new and useful Improvements in Portable Ovens; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in portable ovens, the object of theinvention being to construct a sheetmetal oven of this character of as few parts as possible and at the saine time to construct an oven of neat and attractive appearance, strong and durable,and air-tight,(as faras it is desirable to so make an oven having an open bottoni 5) and with this object in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in elevation illustrating my improvements with the door open. Figs. 2 and 3 are views in section of the same. Figs. 4, 5, and 6 are detail views of the several blanks, and Figs. 7 and S are views illustrating a modified form of my improvements.

1 represents the blank from which the top, sides,and bottom are formed,2 the blank forming the back, and 3 the blank strip to be secured to the lower edge of the front.

In constructing the oven the blanks above mentioned are first formed and blank 1 slit, forming flanges at both edges,and the blank is then bent on the dotted lines of said Fig. 3, forming a rectangular casing, comprising the top, sides,and bottom,which latteris made with an openings and is secured by rivets or otherwise to a flange 5 on the lower edge of one of the sides. The fianges 6 at the rear of the top, sides, and bottom are bent at an angle, and the flanges 7 on the blank 2 (forming the back) are placed thereagainst, and said fianges double seamed and flattened against the back. The flanges 8 on the front edge of the top, sides,and bottom are bent inward, overlapping each other at their ends,

5o the flanges at the upper corners of the oven beingpreferably riveted together,and to the lower portions of the flanges on the front edges of the sides and to the flange on the bot.- tom the strip or blank 3 is secured by rivets. Adoorof any approved construction is hinged to the front to close the opening therein, and a suitable deflector is located in the oven to deflect the heat entering through the open bot tom throughout the entire oven.

In Figs. 6 and 7 Ihave illustratedaslightlymodified form of my invention, in which the blank 14 comprises only the top and sides and is flanged at each end and bent inward, as shown at l5, forming a portion of the bottom. The rear portion of the bottom is formed by a flange 16 on the back secured to the flanges l5, and the front portion of said bottom is formed by a blank 17, bent longitudinally and secured at the lower front corner of the casing, forming a portion of the bottom and the lower closed portion of' the front. The back is secured to the flanges at the rear of the top and sides by double-seaming'and attenin g the seam against the back, as above explained, and in all other respects this form of my invention is like the preferred form described. y

A great many other slight changes might be resorted to in the general form and arrangement of the several parts described Without departing from the spirit and scope of my invention, and hence I would have it understood that I do not limit myself to the preoise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An oven-casing comprisinga sheet-metal blank bent to form the top and sides of the casin g and fianges at the front and rear edges of said top and sides, a back having a flange at each of its edges, all of said flanges on the back secured to the flanges at the rear edges of the top and sides, fastening devices securing the fianges at the front of top of the oven to the fianges of the sides, a separate strip connecting the lower portion of the side at one end to be secured to the bottom, flanges 1o at the rear of said top, bottom and sides, a back, Iianges on said back seamed to said first-mentioned flanges, anges on the front edges of the top, sides and bottoin, the top flange being secured to the side flanges and a strip secured at its ends to the lower portion of the side anges and partially closingv the opening in the front of the casing.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

JOHN R. CARTER.
